问题
I am new to proxy classes. I thought visual studio just handled them and never thought about them again. Now, I am having problems.
When running my Xamarin.Forms App on iOS, it throws this error when calling my WCF:
MonoTouch does not support dynamic proxy code generation. Override this method...(etc)
So in the proxy code, I created this method:
protected override IService1 CreateChannel()
{
return new Service1ClientChannel(this);
}
But the return Service1ClientChannel is not recognized. What do I put for the return object? Since I am new to proxy classes, if you can't answer that question, then what is a good resource to learn about creating/editing them myself? Thanks in advance.
Below is more of the proxy code for some context:
public partial class Service1Client : System.ServiceModel.ClientBase<IService1>, IService1
{
public Service1Client()
{
}
protected override IService1 CreateChannel()
{
return new Service1ClientChannel(this);
}
public Service1Client(string endpointConfigurationName) :
base(endpointConfigurationName)
{
}
public Service1Client(string endpointConfigurationName, string remoteAddress) :
base(endpointConfigurationName, remoteAddress)
{
}
public Service1Client(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) :
base(endpointConfigurationName, remoteAddress)
{
}
public Service1Client(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) :
base(binding, remoteAddress)
{
}

回答1:
The solution was to define the "Service1ClientChannel" class myself:
private class Service1ClientChannel : ChannelBase<IService1>, IService1
{
public Service1ClientChannel(System.ServiceModel.ClientBase<IService1> client) :
base(client)
{
}

}
public IAsyncResult BeginCheckIfUserNameExists(CheckIfUserNameExistsRequest request, AsyncCallback callback, object asyncState)

_args[0] = request;
return (IAsyncResult)base.BeginInvoke("CheckIfUserNameExists", _args, callback, asyncState);
}
public IAsyncResult BeginCreateUser(CreateUserRequest request, AsyncCallback callback, object asyncState)

}
